A novel fluorescence technique for identification of the pulmonary segments by using the photodynamic diagnosis endoscope system: an experimental study in ex vivo porcine lung.
Photodynamic diagnosis is a technique that has been proposed to enhance tumor detection and resection. We modified this technique to identify pulmonary segments and examine the feasibility of this technique in ex vivo porcine lungs. ⋯ This florescence technique using vitamin B2 and the photodynamic diagnosis endoscope system is useful to identify the target pulmonary segment easily and clearly in ex vivo porcine lung.

Risk stratification and prognostic effects of internal thoracic artery grafting during acute myocardial infarction.
Surgeons are occasionally requested to perform coronary artery bypass grafting during acute myocardial infarction. We intended to test the safety of coronary artery bypass grafting and internal thoracic artery grafting early after myocardial infarction using the Society of Thoracic Surgeons database. ⋯ Coronary artery bypass grafting less than 24 hours after myocardial infarction carries a higher operative risk but can be performed safely in selected patients. Although confounding variables may exist, internal thoracic artery grafting was associated with improved outcomes. Internal thoracic artery use in this setting is less than ideal, and taking time to harvest internal thoracic artery grafts in patients with acute myocardial infarction might be encouraged.

Effect of preoperative renal function on long-term survival after cardiac surgery.
The study objective was to investigate the effect of renal failure on intermediate-term survival in cardiac surgery patients. ⋯ The results of our study have shown that preoperative renal dysfunction is an independent predictor of long-term mortality in cardiac surgery patients.

Comparative StudyCost-effectiveness of the Edwards SAPIEN transcatheter heart valve compared with standard management and surgical aortic valve replacement in patients with severe symptomatic aortic stenosis: a Canadian perspective.
The primary analysis estimated the cost-effectiveness of transfemoral transcatheter aortic valve implantation (Edwards SAPIEN heart valve; Edwards Lifesciences LLC, Irvine, Calif) compared with standard management in inoperable patients with severe, symptomatic aortic stenosis. The secondary analysis estimated the cost-effectiveness of transcatheter aortic valve implantation (transfemoral or transapical approaches) (SAPIEN heart valve) compared with surgical aortic valve replacement in operable patients with severe, symptomatic aortic stenosis. ⋯ This economic evaluation suggested that transfemoral transcatheter aortic valve implantation was a cost-effective option compared with standard management for inoperable patients with severe, symptomatic aortic stenosis, but it might not be a cost-effective treatment compared with surgical aortic valve replacement for operable patients.
